Abstract
The invention discloses a kind of low ground resistance earth devices, comprising: ground line；It is characterized in that, the low ground resistance earth device further include: buried line；The buried line includes two or more, and buried line is the metal bar of surface exposure, is electrically connected in buried line embedment soil layer and with ground line lower end, parallel with one another between buried line.With solve the problem of the prior art by sprinkle salt water reduce ground resistance cause ground resistance to be less than the standard requirements duration is not long and ground line easily corrodes causes ground resistance to increase.
Description
Technical field
The present invention relates to field of electrical equipment more particularly to a kind of low ground resistance earth devices.
Background technique
Existing ground structure, such as the ground structure of lightning rod, electrical equipment and transformer are embedded in soil layer for one
Electric wire, in most cases this ground structure is simple and effective, but under certain geological conditions soil conductivity compared with
Low, causing ground resistance to be greater than standard requirements cannot meet the requirements, and existing way is that salt is sprinkled in being grounded buried soil layer
Water to reduce ground resistance, but sprinkle salt water the problem is that: first is that the duration is not grown, salt can be washed with rainfall,
Ground resistance is restored to standard requirements or more again after heavy rain；Second is that salt is attached on ground line, to generate primary battery anti-
It answers, makes ground line corrosion that ground resistance be caused to increase.
Summary of the invention
The technical problem to be solved by the present invention is a kind of low ground resistance earth device is provided, to solve the above problems.
The technical scheme is that a kind of low ground resistance earth device,
Include:
Ground line；
It is characterized in that,
The low ground resistance earth device further include:
Buried line；
The buried line includes two or more, and buried line is the metal bar of surface exposure, in buried line embedment soil layer and with connect
Ground wire lower end is electrically connected, parallel with one another between buried line.
The buried line further include:
Conductive nematophore；
The conduction nematophore is fixedly connected on buried line surface.
The ground line surface covers one layer of anti-corrosion conductive material.
The transformer grounding structure further include:
Graphite powder electric conductor；
The graphite powder electric conductor includes the graphite bisque being buried in soil layer；
In the buried line embedment graphite powder electric conductor.
The graphite powder electric conductor further includes protection body；
The protection body is the mixed mud box being buried in soil layer, and graphite bisque is in mixed mud box.
The graphite powder surface layer is 0.2m2~0.3 m2。
The beneficial effects of the present invention are:
Compared with prior art, 2 or more buried lines by being embedded in soil layer by the present invention, and will be grounded lower end and buried line
Connection, increases the contact area of ground line and soil layer, so that transformer grounding resistance is dropped to standard requirements hereinafter, the present invention
Ground resistance effectively can be reduced to standard requirements or less for a long time.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
With reference to the accompanying drawing and invention is described further in specific embodiment:
With reference to Fig. 1, a kind of low ground resistance earth device,
Include:
Ground line 2；
It is characterized in that,
The low ground resistance earth device further include:
Buried line 5；
The buried line 5 includes two or more, and buried line 5 is the metal bar of surface exposure, buried line 5 be embedded in soil layer 4 and
It is electrically connected with 2 lower ends of ground line, it is parallel with one another between buried line 5.
In use, connect by the way that 2 or more buried lines 5 are embedded in soil layer 4, and by 2 lower ends of ground line with buried line 5,
The contact area for increasing ground line 2 with soil layer, so that transformer 1 or other electrical equipment ground resistances are dropped to standard requirements
Hereinafter, ground resistance effectively can be reduced to standard requirements or less for a long time by the present invention.
The buried line 5 further include:
Conductive nematophore 6；
The conduction nematophore 6 is integrally formed or is welded to connect on buried 5 surface of line.
Conductive nematophore 6 further increases the contact area of buried line 6 and soil layer 4, further reduced ground resistance.
2 surfaces of the ground line cover one layer of anti-corrosion conductive material.It is equivalent in parallel to transformer 1 or other electrical equipments
One piece-root grafting ground wire lives to be grounded 2 additionally, due to this anti-corrosion conductive wrap, and avoiding rainwater and soaking ground line 2 makes it
It is corroded.
The transformer grounding structure further include:
Graphite powder electric conductor 3；
The graphite powder electric conductor 3 includes the graphite bisque 301 being buried in soil layer 4；
The buried line 5 is embedded in graphite powder electric conductor 3.
By being embedded to graphite bisque 301 in soil layer 4,2 lower ends of ground line and graphite bisque 301 are directly connected, and are increased
The contact area for having added ground line 2 with soil layer 4, so that transformer 1 or other electrical equipment ground resistances are dropped to standard requirements
Hereinafter, ground resistance effectively can be reduced to standard requirements or less for a long time by the present invention.
The graphite powder electric conductor 3 further includes protection body 302；
The protection body 302 is the mixed mud box being buried in soil layer 4, and graphite bisque 301 is in mixed mud box.
By protection body 302, one to can be prevented from graphite bisque 301 washed away, second is that powder can be destroyed to avoid external force
The graphite bisque 301. of last shape fragility
301 surface area of graphite bisque is 0.2m2~0.3m2。
So that volume excessive will not waste while transformer 1 or other electrical equipment ground resistances are less than standard requirements
Graphite powder.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
